Thx for the input. I did as you said and used program to rezise all my fanart to 845 x480 and it work perfect now.

Is is possibly to have the overlays with info om what the boxes are ,so when the movies is focuse ther is a over lay saying "watch your movies" but all boxes behind is just showing the fanart, it would be nice to see the overlay on the other to . And i think it would look better if the focused one only changed its fananrt instead all of them at the same time. becouse it looks lite strange when i scroll in the meny and alot of changes is happening all the time in the background instead and taking some focues away from the one you should be looking on.
Hope you understand what i am talking about
